Asset Performance Management at Tenaga Nasional Berhad Power Plants

Project Summary

Project
Over the years, Tenaga Nasional Berhad (TNB), the largest electricity utility in Malaysia, implemented a number of asset performance enhancement initiatives such as reliability centered maintenance, generation plant management, enterprise resource management, and predictive maintenance. However, vital information from these initiatives was contained in multiple databases or paper records.TNB launched a program to centralize all condition-based information to gain insights and ensure timely and accurate decisions.

Solution
Bentley’s AssetWise was implemented at TNB’s 10 power plants to integrate the various initiatives into a coherent business process. This software now provides a single platform that captures real-time plant data from TNB’s PI System, data from local gauges, data from the condition monitoring task, and transactional data from SAP. Thus, TNB can now instantly assess the health condition of the asset, enabling engineers to make more timely and informed decisions about interventions, reducing reactive maintenance.

Outcome
The asset performance management (APM) initiative reduced the risk of plant failure and downtime, as well as the risk of major equipment faults or failures. Efficiency gains are achieved through improved planning and scheduling of the right work at the right time. With fewer outages, TNB can produce uninterrupted power for its customers.
Software
The integrated APM system is a centralized source of critical information aiding analysis, strategic development, and decision-making. Most importantly, the effectiveness of an implemented maintenance strategy can be gauged and evaluated based on results metrics (lagging indicators) and proactive process metrics (leading indicators) of the asset.
